The method disclosed can be used to track individuals still remaining in a building in case of an emergency. The method comprises determining a location for an individual by receiving a device identifier (e.g., combination of numbers and/or characters uniquely identifying a receiving device associated with the individual) and location information, received from one or more beacons, from the receiving device. The method comprises determining a first location associated with the receiving device based on the location information and/or the device identifier. The method comprises determining different locations associated with the individual as the individual moves and determining whether the individual is still within the building. The method comprises, displaying location information and instructions to reach the individual in case of an emergency. ## Claims ### Claim 1 A method comprising: monitoring, by a server, location associated with a first mobile device by: periodically receiving, by the server, a set of location information from the first mobile device, wherein the set of location information is received, by the first mobile device, from a plurality of beacons within a building; and periodically determining, by the server, the location associated with the first mobile device based on the set of location information; receiving, by the server, from a second mobile device, a request to identify one or more mobile devices within the building; determining whether a current location associated with the first mobile device is within the building, wherein the current location of the first mobile device is associated with a location of the first mobile device at a time period that the server receives the request from the second mobile device; and upon determining that the current location associated with the first mobile device is within the building, transmitting, by the server, the current location associated with the first mobile device to the second mobile device, whereby a graphical user interface associated with the second mobile device displays the current location associated with the first mobile device. ### Claim 2 (depends on 1) The method of claim 1, wherein the graphical user interface further comprises identification information associated with a user operating the first mobile device. ### Claim 3 (depends on 2) The method of claim 2, wherein the identification information comprises one or more medical conditions associated with a user operating the first mobile device. ### Claim 4 (depends on 1) The method of claim 1, wherein the graphical user interface further comprises instructions to reach the current location associated with the first mobile device. ### Claim 5 (depends on 4) The method of claim 4, wherein the instructions to reach the current location associated with the first mobile device comprises a fastest route to the current location associated with the first mobile device. ### Claim 6 (depends on 4) The method of claim 4, wherein the instructions to reach the current location associated with the first mobile device comprises a route comprising one or more points of interest within the building. ### Claim 7 (depends on 1) The method of claim 1, wherein the graphical user interface is transmitted to the second mobile device through an encrypted transmission method. ### Claim 8 (depends on 1) The method of claim 1, wherein the graphical user interface comprises a request for identification confirmation by a second user operating the second mobile device. ### Claim 9 (depends on 8) The method of claim 8, wherein the identification confirmation is in form of a password. ### Claim 10 (depends on 8) The method of claim 8, wherein the identification confirmation is in form of biometric data. ### Claim 11 A computer system comprising: a plurality of beacon within a building, wherein each beacon is configured to periodically transmit location information; a first mobile device configured to receive location information from at least one beacon; a second mobile device in communication with a server, wherein the server is configured to: monitor location associated with the first mobile device by: periodically receiving a set of location information from the first mobile device, wherein the set of location information is received, by the first mobile device, from the plurality of beacons within a building; and periodically determining the location associated with the first mobile device based on the set of location information; receive, from the second mobile device, a request to identify one or more mobile devices within the building; determine whether a current location associated with the first mobile device is within the building, wherein the current location of the first mobile device is associated with a location of the first mobile device at a time period that the server receives the request from the second mobile device; upon determining that the current location associated with the first mobile device is within the building, generate a graphical user interface configured to display the current location associated with the first mobile device; and transmit the graphical user interface to the second mobile device. ### Claim 12 (depends on 11) The computer system of claim 11, wherein the graphical user interface further comprises identification information associated with a user operating the first mobile device. ### Claim 13 (depends on 12) The method of claim 12, wherein the identification information comprises one or more medical conditions associated with a user operating the first mobile device. ### Claim 14 (depends on 11) The method of claim 11, wherein the graphical user interface further comprises instructions to reach the current location associated with the first mobile device. ### Claim 15 (depends on 14) The method of claim 14, wherein the instructions to reach the current location associated with the first mobile device comprises a fastest route to the current location associated with the first mobile device. ### Claim 16 (depends on 14) The method of claim 14, wherein the instructions to reach the current location associated with the first mobile device comprises a route comprising one or more points of interest within the building. ### Claim 17 (depends on 11) The method of claim 11, wherein the graphical user interface is transmitted to the second mobile device through an encrypted transmission method. ### Claim 18 (depends on 11) The method of claim 11, wherein the graphical user interface comprises a request for identification confirmation by a second user operating the second mobile device. ### Claim 19 (depends on 18) The method of claim 18, wherein the identification confirmation is in form of a password. ### Claim 20 (depends on 18) The method of claim 18, wherein the identification confirmation is in form of biometric data.
